Tobias, I think it needs to go farther down to just before here:
/* Select a width if none was specified. The idea here is to always
print something. */
The standard says to ignore the w.d in the G descriptor, so I think we want to
be past after this:
if (m == 0 && n == 0)
{
if (w == 0)
w = 1;
p = write_block (dtp, w);
if (p == NULL)
return;
memset (p, ' ', w);
goto done;
}
Otherwise w will get set to 1 and not get ignored.
Also you example uses a0 which is also rejected. I have a patch for that.
